Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We assume that all files are saved to a top-level directory called code and the main.cpp file is saved inside the /code/Tutorial1 subdirectory."

A block of code is set as follows:

typedef struct
{
  GLfloat x, y, z;
} Data;

Any command-line input or output is written as follows:

sudo port install glfw

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Check the Empty project option, and click on Finish."
